The post is available as part of the PEROXIS project granted through H2020-ICT5.
Hybrid organic-inorganic perovskite materials are attracting a lot of attention due to their unique properties leading to record efficiencies in photovoltaics. Beyond the original application as solar cells, recent interest has emerged regarding their use as sensitive layer for the direct detection of ionizing radiations. Based on INAM expertise in several perovskite-based technologies, we have initiated a research line aimed at exploring the potential of CH3NH3PbBr3 for the detection of X-rays. More specifically, we propose to realize an X-ray imaging device where a thick, poly- and single-crystal perovskite layer on a pixelated substrate would realize the direct conversion of X-rays into charge carriers. This would allow medical radiography with higher spatial resolution and higher sensitivity while lowering the patients’ dose. This study has received the financial support of the European Commission through a H2020-ICT5 grant.
The pre-doctoral student will be involved in device testing, modeling and simulation of detectors (single diode) using advanced optoelectronic measuring tools. These electronic techniques include impedance spectroscopy, analysis of transient signals, as well as more traditional electronic parameter extraction tools as time-of-flight, and other charge transport properties. The relation within the EU consortium with specialists of integration and device fabrication and characterization will be maintained and exploited to assure the structural quality (type and number of defects) of the detector materials.
The project is coordinated by Prof. Germà Garcia-Belmonte. Please, check Research Division at INAM (http://www.inam.uji.es/).
There is a Position for a Graduate (Bachelor and Master) on Physics or Engineering.
The PhD student will develop an experimental work. Candidate with a strong interest for experimentation, electronic testing and device physics is expected. Skills in semiconductor processing and measuring are needed. Expertise in hybrid perovskite materials and device processing and electronic characterization would be welcome.
Experience with some of the preparation and characterization techniques above described will be important.
- Processing of materials and devices for electronics (specially halide perovskites).
- Experience in thin film deposition by different techniques (specially evaporation).
- Fabrication of optoelectronic devices (specially on solution deposition methods).
- Experience with structural, chemical, optical or electrical characterization of materials and optoelectronic devices.
- Modeling of solid-state devices.
General skills requested are:
• Strongly motivated to develop a scientific research career.
• Excellent results obtained during the studies graduated.
• Excellent interpersonal and communication skills.
• Fluent in English.
